Question

Draw the graph of $I_{rms}\to \omega$ for an A.C., L-C-R series circuit and hence explain Q-factor.

Answer 1

The graph shows variation of current $I_{rms}$ with angular frequency $\omega$

The Q factor is a dimensionless parameter that indicates the energy losses within a resonant element which could be anything from a mechanical pendulum, an element in a mechanical structure or within electronic circuit such as resonant circuit.
